/dev/sdc1 and /dev/sdd1 is raided (RAID1) into /dev/md3. /dev/md3 is encrypted with luksSetup.
Last night I got DegradedArray events for /dev/sdc1. I shutdown the system, physically removed the disk, and booted back up again. Now there is no md3 according to /proc/mdstat
$ mdadm --detail /dev/md3

- 0 0 0 removed
1 8 49 1 active sync /dev/sdd1
The physically remaining disk (the working one) is now called /dev/sdc. The partition type of /dev/sdc1 is "Linux RAID autodetect". I cannot open this with luksOpen, it doesn't even ask for password.
How can I physically remove the broken disk and keep using the working one? Right now I must keep the broken disk physically connected to the server to be able to continue using the working one.

Make sure that grub is installed on the second drive and switch your BIOS settings to boot from active disk.
You can install GRUB with:
sudo grub-install /dev/sdd
sudo update-grub2
